Prostate volume was calculated using the ellipsoid formula: ((p/6)×transverse×length×height). Results: Thirty‐three prostatic urethral casts were obtained. The mean prostate volume was 38.59cc. The mean PUA was 127.6°. The mean transverse, apex, and length of the prostate were 4.65, 4.06, and 3.63cm, respectively. The mean distance

Prostate weight is the preferred measure of prostate size ...
measures of prostate size: volume and weight. Whereas prostate weight is a direct measurement on scales, prostate volume is routinely derived by applying the prolate ellipsoid formula to three measured dimensions of the prostate [ 6 ] . A third measure of prostate size is the preoperatively measured TRUS volume,

ellipsoid volume calculation available on Bruel & Kjaer and Hitachi scanning systems. We now recognize that the prolate ellipse volume calculation is more accurate than the "ellipsoid' technique and is the best approxi- mation of planimetry values.'6 Because 7.5-MHz trans- ducers are limited for proper evaluation of glands

measure prostate volume: planimetry calculation, prolate ellipse volume calculation, and ellipsoid volume measure-ment [2]. Among them, prolat e ellipse volume calculation is commonly used because it is fast and precise. It is calcu-lated as follows: prolate ellipse volume (cm)=(length× width×height)×π/6. Length refers to the longitudinal di-

instruments, using a 7.5 MHz rectal probe. Prostate volume was always determined using a standard prolate ellipsoid volume formula [21] (automatically calculated by software integrated in the ultrasound machine) based on measurements in the transversal and sagittal views. 2.1. Statistical analysis

Outcomes of HoLEP in the Retreatment Setting
The ellipsoid volume formula (volume = length × width × height × π/6) was used to calculate prostate volume. Urodynamics prior to HoLEP were performed at the discretion of the treating urologist. T D ACCEPTED MANUSCRIPT A standardized HoLEP was performed using the previously described technique by one

estimating prostate volume by TRUS, provides a more accurate value of the true prostate volume. Keywords: Prostate volume, Trans-rectal ultrasound, Ellipsoid, Bullet, Formula, Coefficient Background Prostate volume is an important parameter used by clinicians to better manage patients with lower urinary tract symptoms (LUTS) or cancer.

Prostate volume estimation was done using the El-lipsoid Prostate Volume Formula. The ellipsoid model is the original and de facto standard method of calcu-lating the prostate volume. The greatest three dimen-sions of the prostate on axial and coronal T 2-weighted MRI images were measured manually and these measurements were used to determine ...

Ellipsoid Prostate Volume Determination The greatest three dimensions of the prostate on MRI was measured manually and these mea-surements were used to determine the volume es-timate of the prostate using the ellipsoid formula: (SI × AP × RL × 0.52), where SI is the superoinferior dimension; AP, antero-posterior dimension; and RL, right-left ...
